Distribution Network Design Savings Calculator — DC Optimisation

Calculate freight savings from optimising your distribution network. Find how adding or repositioning distribution centres reduces last-mile freight cost and transit time.

Quick answer: Adding a strategically located DC typically reduces average freight cost per package by $0.50–$2.50 by shifting packages from zone 7–8 to zone 2–4. On 500K packages/year: $250K–$1.25M potential saving minus DC operating cost.

How to Use This Calculator

  1. Analyse your current zone distribution — pull zone data from your carrier's shipment reports — what's your weighted average zone today?
  2. Model new zone distribution — use carrier zone maps to estimate the average zone if you had a DC in the target location.
  3. Include all DC costs — lease, labour, systems, and the additional inventory carrying cost from splitting stock.

Worked Example

500K packages/year, zone 6 → zone 4, $1.20/zone, $850K DC cost, $120K inventory.

  1. Zone improvement: 2 zones
  2. Freight saving: 2 × $1.20 × 500K = $1,200,000
  3. DC + inventory cost: $970,000
  4. Net saving: $230,000/yr. Payback: 0.8 years

Network optimisation is one of the highest-ROI supply chain investments for e-commerce at scale. At 500K+ packages/year, the math almost always works. Use free carrier zone lookup tools to map your customer base before building the business case.

Frequently Asked Questions

Rule of thumb: 1 DC serves zones 1–3 within 2 days ground for ~30% of the US population. 2 strategically located DCs (e.g., East and West) cover 70%+ in 2 days ground. 3 DCs (East, Central, West) achieve 90%+ in 2 days. Each additional DC reduces average zone but adds operating cost — model the break-even for your volume.

Popular dual-DC pairs: (1) Columbus/Harrisburg OH/PA + Reno/Las Vegas NV — covers ~75% of US in 2 days ground. (2) Memphis TN + Los Angeles CA. (3) Atlanta GA + Phoenix AZ. Optimal location depends on your customer concentration — use carrier zone lookup tools mapped against your order history.
